APPARATUS FOR RAISING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 642,968, dated February6, 1900.

Application filed September 20, 1899. Serial No. 731,092. (No model.) I

To a whom it may concern.-

Be it known that LRALPH WALDO ELLIOTT, of Oakley, in the county ofContra Costa and State of California, have invented a new and ImprovedApparatus for Raising Liquids, of which the following is a full, clear,and exact description.

The invention relates to apparatus for raising liquids, such as shownand described in the Letters Patent of the United States No. 597,273,granted to me on January 11, 1898.

The object of the present invention is to provide a new and improvedapparatus for raising liquids which is simple and durable inconstruction and arranged to automatically control the motive agent usedfor forcing the liquid from a lower to a higher level.

. The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claim.

A practical embodiment of my invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a sectional side elevation of the improvement. Fig. 2 is alike view of the same with parts in a different position, and Fig. 3 isa sectional plan view of the same on line 3 3 in Fig. 1.

The improved apparatus for raising liquids is provided with a vessel A,submerged in the liquid to be raised and provided at its bottom with aself opening and closing inletvalve B for admitting liquid to the vesselA, as hereinafter more f ully' described. The liquid in the vessel A isdischarged through a pipe 0, carrying at its lower enda self opening andclosing inlet-valve D, located near the bottom of the vessel A, the pipeG extending upwardly through a cylinder E, arranged on the top of thevessel A and fOI'IIling part of the valve for controlling the motiveagent, such as compressed air, passing through a pipe F from amotive-agent supply to the said cylinder by way of an annular chamber E,having ports or openings E leading to the outside of the cylinder E. Asecond set of apertures or openings F. is arranged above the openings Eand said openings E serve to connect the interior of the cylinder E andthat of the vessel A with the atmosphere. A valve G, in the form of aring, mounted to slide vertically in the cylinder E, is adapted toalternately open and close the sets of openings E E so that when theopenings F. are closed, as shown in Fig. 1, the motive agent is cut offfrom the vessel A, while the interior thereof is connected with theatmosphere by the openings E When the valve Gis in an uppermostposition, as shown in Fig. 2, the openings E are closed and the openingsE are open, so that motive agent can pass into the vessel A to exert apressure on the liquid therein, so as to force the liquid past the valveD into and through the pipe 0 to a suitable place of discharge.

The valve G is provided with rods G, carrying a collar G from whichdepend rods G carrying at their lower ends a collar G and on the rods Gbetween the collars G is mounted to rise and fall a float H, rising andfalling with the liquid in the vessel A and serving to alternatelyengage the collars G and G so as to shift the valve G into the positionshown in Figs. 2 and 1.

The operation is as follows: When the several parts are in the positionshown in Fig. 1, then the motive agent in the pipe F is cut off from theinterior of the vessel A by the valve G, and the liquid in which thevessel A is submerged will now flow into the vessel A by way of thevalve B to fill said vessel A and to cause the float H to rise with theliquid rising in the said vessel A. As the float H moves into anuppermost position it comes in contact with the collar G and finallylifts the same to shift the valve G into the uppermost position shown inFig. 2, whereby the openings F. are closed'and the openings E areopened, so that the motive agent can pass into the vessel A and exertapressure on the liquid therein to force the liquid up through the pipe 0to a place of discharge. Now as the liquid passes out of the vessel Athe float H sinks with the falling liquid and finally comes in contactwith the collar G and moves the same downward and with it the valve G,so that the openings E are again opened. The openings E are closed andthe motive agent shut off. The motive agent under pressure in the vesselA can now pass through the openings F. to the atmosphere, andconsequently the liquid surrounding the vessel A can again pass into thesame by way of the valve B. The above-described operation is thenrepeated.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent An apparatus for raising liquids, coin prisinga vessel having an inlet for the liquid to be raised and provided at thetop with an airinlet and an air-outlet, an apertured valve arranged toalternately close the air-inlet and the air'outlet, a liquid-outlet pipearranged centrally or axially with respect to said valve and passingtherethrough, rods extending downwardly from the valve and providedwit-h collars having guided movement on the liquid-outlet pipe, and afloat movable on said rods between the collars.
